Explore the cosmic aftermath of a neutron star collision. This animation breaks down the detection of a kilonova and explains how such an event can forge a magnetar—a city-sized stellar remnant many ...

Second only to black holes, neutron stars – incredibly dense star remnants – are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time in ...

A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an ...

"We found a collision within a collision. The galaxy collision triggered a wave of star formation that, over hundreds of millions of years, led to the birth and eventual collision of these neutron ...

Astronomers have spotted a jaw-dropping collision between two neutron stars – and it may have produced gold and platinum. The discovery in a tiny, faraway galaxy is the first time this has been seen ...

A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...
